French Tarragon (Artemisia dracunculus var. sativa) is a must-have herb for the discerning gardener and cook. Known for its aromatic leaves and subtle anise-like flavor, this perennial herb elevates sauces, dressings, and roasted dishes. Unlike Russian tarragon, French Tarragon is prized for its superior flavor and is grown primarily through cuttings as it rarely produces viable seeds. Don't worry, we've got you covered.

Planting and Care

French Tarragon thrives in well-drained soil and full sun, making it an excellent choice for garden beds and containers.

• Soil: Ensure soil is slightly sandy or loamy with good drainage. Avoid overly rich soil to prevent legginess.

• Watering: Moderate watering is best; allow the soil to dry slightly between waterings. Overwatering can lead to root rot.

• Fertilizer: A light feeding of balanced fertilizer in spring helps maintain healthy growth. Avoid heavy feeding, as it can dilute the herb's flavor.

• Pruning: Regularly trim to encourage bushy growth and prevent flowering, which can cause the flavor to decline.

Harvesting and Using Tarragon

• Harvest French Tarragon leaves throughout the growing season for fresh use.

• The leaves are best when used fresh but can also be dried or frozen to preserve their flavor.

• Tarragon pairs beautifully with chicken, fish, eggs, and creamy sauces. It’s also a classic ingredient in béarnaise sauce.

Common Pests and Diseases

Tarragon is relatively low-maintenance, but it can face occasional challenges:

• Pests:

  • Aphids: These small insects can cluster on leaves and stems, sucking sap and weakening the plant. Use insecticidal soap or a strong spray of water to dislodge them.

  • Spider Mites: Fine webbing on the plant indicates an infestation. Treat with neem oil or insecticidal soap.

  • Leaf Miners: Small tunnels in leaves can indicate their presence. Remove and dispose of affected leaves.

• Diseases:

  • Powdery Mildew: A common fungal issue that appears as a white, powdery coating on leaves. Prevent by ensuring good air circulation and avoiding overhead watering.

  • Root Rot: Caused by overwatering or poor drainage. Always plant in well-draining soil and avoid waterlogged conditions.
